Dear All:
After installing the packages "car" and "alr3", I got the following
error
messages:
library(car)
Error in library(car) : there is no package called ?car?
library(alr3)
Error in library(alr3) : there is no package called ?alr3?
any helps would be appreciated.
You need to show us the messages you received when you installed them.
The usual cause of problems like this is that you don't have write
permission on the default location, and R has chosen an alternate; then
when you try to attach the packages, you haven't told R to look in the
alternate location.
